Embodiment 1

[0018] Using 75 parts of aluminum silicate fiber as raw material, the aluminum silicate fiber cotton is first beaten for 5 minutes, and the mixture of silica sol and corn starch with a mass ratio of 25 parts of 12:7 is used as the adhesive. After the agent is mixed, it is poured into a decomposer of 900 rad to decompose, and it is made with a paper-making former, and finally vacuum-dried to form a paper sheet.

[0019] Some components of the composite flame-retardant paper sample burned rapidly, and the part burned by an open flame was charred, but some parts of the flame-retardant paper were not burned, and there was no carbonization length. The continued burning time was 8.1S, and the smoldering time was 2.2S. The sample has no trace of burning. After ignition, there are traces of flame smoke on the paper, and the place burned by the flame is softer than the place that has not been burned.

Embodiment 2

[0021] Use 70 parts of aluminum silicate fiber as the raw material to beat for 10 minutes, and use 30 parts of a mixture of silica sol and corn starch with a mass ratio of 14:9 as the adhesive 30. After mixing, pour it into a decomposer at 800 rad to decompose, and use it for papermaking. The former is used for papermaking, and then vacuum-dried to form paper sheets.

[0022] Some components of the composite flame-retardant paper sample burned quickly, and the part burned by an open flame was charred, but some parts of the flame-retardant paper were not burned, and there was no carbonization length. The continued burning time was 8.4S, and the smoldering time was 2.7S. The sample has no trace of burning. After ignition, there are traces of flame smoke on the paper, and the place burned by the flame is softer than the place that has not been burned.

Embodiment 3

[0024] Using 65 parts of aluminum silicate fiber cotton as the raw material, first beat for 15 minutes, and use 35 parts of the mixture of silica sol and corn starch with a mass ratio of 13:8 as the adhesive. The former is used for papermaking, and then vacuum-dried to form paper sheets. Some components of the composite flame-retardant paper sample burned rapidly, and the part burned by an open flame was charred, but some parts of the flame-retardant paper were not burned, and there was no carbonization length. The continued burning time was 8.6S, and the smoldering time was 2.4S. The sample has no trace of burning. After ignition, there are traces of flame smoke on the paper, and the place burned by the flame is softer than the place that has not been burned.

Abstract

The invention provides a flame retardant paper and a production method thereof. According to the method, 35-75 weight parts of aluminum silicate fibers and 5-4 weight parts of adhesives are used as the raw materials; the aluminum silicate fibers are removed dregs, then beaten for 5-30 minutes, mixed with the adhesives, poured into a defibering device with 800-3000rad for defibering, and subsequently made into papers by using a paper making forming device; and the papers are dried by vacuumizing to form paper sheets. The flame retardant packaging paper is produced by using aluminum silicate fiber compound papers instead of plant fibers and traditional flame retardants, is environment-friendly, and has good flame retardant effect, and the problems of using toxic substances, polluting environments, having poor flame retardant effect and the like during production of flame retardant packaging papers are avoided.

Description

technical field [0001] The invention relates to a flame-retardant paper. The invention also relates to a preparation method of flame-retardant paper. Background technique [0002] As we all know, "Fire cannot be contained in paper". Paper is generally made of plant fibers, which are organic and flammable. The flammability of paper products limits the scope of application of the product. Paper is flammable, and after special treatment, it can be non-combustible, which increases the application range of paper products. At present, flame retardant wrapping paper can be used in the following aspects: surface laminating materials, core filling materials, microwave oven food heating bags, packaging materials for electrical appliances, concierge, flower tube paper packaging products, lantern paper, etc. [1, Li Chao et al., Research on the Preparation of Flame Retardant Paper from Magnesium Aluminum Hydrotalcite, Zhonghua Paper Industry, 2011(1)] [0003] Existing flame-retarda...
